I mean, if they really wanted to make money off us, they can easily say R&R every 30k miles. I feel technology these days has definitly improved within the last 15-20 years. Oil changes are now every 5k, T-belts 120k also now. Fuel filters are never changed cuz now most are in the tank. No more distributors. I think Toyota is nice enough to not rip us off that bad =)
my 2cents

Actually no.
Auto maufactures are always telling the public that their cars are more maintenance free than the compitition's. It just plain marketing.

This is why they are all telling owners to leave things like oil and plugs in a bit longer than they should. Those are the two main engine maintenance items.
Once one maufacturer does,they all have follow to stay competitive.

Yeah, modern oil and plugs have a longer sevice life than in the past.
However, the maintenance schedules are pushing the limits a bit....IMO
Maintenance schedules are designd fot "normal" driving but, few cars fit that catagory exactly.......more marketing.
